I really don't know what these types of articles really serve for. If you read a bit into it, here is what it says:
Such claims really annoy me. As if their precious credit cards haven't been hacked many times before. Speaking about hacking, each time you make an online purchase with your credit card, your number and pin are being transmitted along with your private data. Unlike Bitcoin, where you keep your private key always safe by your side.
I do agree that the contents of the article are suspect once reading into it. But how many people actually read into articles. We live in a very headline driven society at the moment and my guess is that that majority of people will only read headlines. We are in an environment where 99% of coverage is negative surrounding crypto so its quite nice to see some positive fake news every now and then instead of fake news bashing the industry. I do share your concern though but at least its not another negative headline.
